Covert Hunter
A new breed of super recurved hunting bows, exceptionally fast, stable, smooth and incredibly quiet. Designed with the most compact working envelope. Ready for action in the tightest of spaces. Covert Design Overview Covert Hunter Product Overview 1st Jan 2014 You have our thanks for considering our products, that alone has great significance for us. Our efforts are focused on producing the very best possible. Producing the best, covers everything we do, but mainly manifests itself in our products. We suggest that you approach this new and exciting bow with an open mind as the CH design is unique and different from conventional designs. Covert Hunter is a holistic view of the bowhunters’ needs and creates a bow that tries to answers all of the needs of the archer in the field. Speed -- The Covert Hunter is able to shoot heavier arrows at similar speeds or faster that most hunting bows achieve with lighter arrows. This major factor improves the hunters reach, accuracy and with higher arrow momentum, improves the likely out come of any encounter. The Covert Hunter design stores more energy than conventional designs and means that lower bow weights can be considered. This feature enables the archer to dominate the bow weight, better improving accuracy. Refer to graphs later on in this overview Smoothness of draw – Covert Hunter has an exceptional draw-force curve with the pounds per inch gained over the last few inches of draw hovering around the 1lb per inch for bow weights commonly employed in hunting. Refer to the Inch Increment graphs farther on in this presentation! Low weight gain over the last few inches of draw has several positive factors, the first is that it may enable the archer to increase bow weight slightly for even higher outputs and still maintain that all important and full concentration on the point to be hit on target. This feature also helps to increase the pleasure when shooting and this stimulates more practice, fuelling further improvements in accuracy. However the main advantage that I personally would consider is that it enables a fuller concentration on the execution of the shot as there is less distraction resulting from the accrued bow weight on the shoulders when coming to anchor at full draw. Accuracy is the prime objective! Stability - The bow displays remarkable lateral and vertical stability emanating from the level of torsional stability crafted into the limbs and the extensive design work that went into the recurve design. This makes the CH very tolerant of arrow spine and shooting technique variations. The deep set deflexed geometry lets the bow settle better during the shot and reduces the effect of bow –hand torque . All in all a very forgiving bow to shoot! Working envelope - The Covert Hunter has the most compact working envelope of any hunting bow we know of, bow length for bow length and this feature is an integral objective of the design that has been met in full. A poignant example of this is that the 60”Covert Hunter has an overall length when braced of only 53.5”. Most conventional 60” recurves, the overall length would be approximately 57”. The Covert Hunter over the full range of bow lengths available have effective working envelopes equivalent to conventional recurves of approximately two bow lengths shorter but have the same string angles at full draw of full length bows. The advantages are smoother more consistent release, giving greater control and accuracy. A “no compromise” answer to accurate and comfortable shooting from the tightest of shooting space! Contents.

Heavier arrows are more stable to shoot and react less to shooting variations and the elements such as wind and rain. Heavier arrows travelling at the same speed as lighter shafts will have a flatter trajectory as they maintain speed through the air better and so achieve a higher average speed and so a better balanced trajectory. The complete arrow weights depicted are absolute minimums and we would recommend using arrows at least 10% heavier. Operating your bow at the minimums may reduce the effective life of the limbs. These minimums are supported by our warranty cover. Shooting arrows below these weights voids warranty. Note - shooting bows, all bows, with absolute minimum arrow weights and at the highest recommended brace heights, in addition using the shortest recommended bow length with highest riser to limb ratio for the longest possible drawlength will certainly shorten your bow’s useful life. Each of these individually is okay but operates the bow at maximums however the combination of all or some of these will overload your bow and risks shortening the useful life of the limbs!

Get it wrong and it can lead to injury sometimes severe and or a broken bow. Bow failure caused by a bow destringing itself is always self evident in that the bow facings are usually intact but the cores are ripped through not along glue lines but through the materials itself. Bow failure often occurs some weeks or even months after the incident. Obviously damage caused by inappropriate handling is not supported by warranty but we do support through our Crash Replacement Support Program CRSP. So it is vital to spell out what is correct and what is not and why. Correct bow stringing for Border bows is best achieved with the stringer provided as per the picture. The pocket should encapsulate the string and bow nock ensuring that the string is properly in the string grooves the rubber faced loop should be on other limb as shown and both feet should be on the stringer about shoulder width apart or slightly wider. This ensures that the stringer has a good angle of attack on the bow limbs and helps prevent the rubber faced loop sliding. Allowing the rubber faced loop to slide will eventually wear the surface finish and should be avoided. This is a simple task by supporting the loop end while the stringer is taking the tension during the initiation and again on the let down. The bow will string easily just as every other bow does. Methods to be avoided at all costs is the push-pull method. The super recurves are too deep for this to be achieved safely. The step through method historically has been responsible for many a twisted bottom limb. This is possible with Border limbs but unlikely due to the significant torsional stiffening crafted into our limbs. However if done carelessly then damage can occur to the nocks being forced into the ground and or the metal work normally found on boots damage the surface of the limbs. This method is much safer than the push-pull method however never as secure as in the proper use of a bow stringer. Covert Hunter Risers Available in riser lengths from 17”, 19” , 21”, 23” and 25” this combined with four limb lengths accommodates bow from 58” through to 72”. Riser wood species selection - our only stipulation is that one of the woods has to be Shedua the same rule we have with our Classic Black Douglas series. This rule ensures a match between every limb and riser set throughout the World and improves the resale value of limbs and risers, enabling our customers to trade on into the used market and helps defend the residual value Black Douglas and Covert Hunter bows and bow components as they trade up or down as their archery develops. Optional woods are Honduras Walnut, Santos Rosewood , Indian Rosewood, Zebrano, Bubinga, European Walnut, Mulberry and Bocote, Cocobolo as and when available. Engineered woods are Heritage Midnight, Heritage Cocobolo, Heritage Walnut, Mountain Camo, Desert Camo, Jacaranda and Heritage Bloodwood to name but some.

The recent practice of over harvesting certain species has led to severe shortages of Cocobolo, Bocote, Macasser Ebony and many more, threatening the sustainability of these tree species!
